Study Notes
Definition of Science
- Systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.
Branches of Science
-
Natural Sciences
- Focus on the physical world and its phenomena.
- Subdivided into:
- Physics: Study of matter, energy, and their interactions.
- Chemistry: Study of substances, their properties, and reactions.
- Biology: Study of living organisms and their interactions with the environment.
-
Formal Sciences
- Study of abstract concepts and systems.
- Includes:
- Mathematics: Study of numbers, quantities, and shapes.
- Logic: Study of reasoning and argumentation.
- Statistics: Study of data analysis and interpretation.
-
Social Sciences
- Study of human behavior and societies.
- Includes:
- Psychology: Study of mind and behavior.
- Sociology: Study of social behavior and structures.
- Economics: Study of production, distribution, and consumption of goods.
Scientific Method
- Systematic approach to inquiry:
- Observation: Gathering data about a phenomenon.
- Question: Formulating questions based on observations.
- Hypothesis: Proposing a testable explanation.
- Experimentation: Conducting experiments to test hypotheses.
- Analysis: Analyzing data collected during experiments.
- Conclusion: Drawing conclusions and refining hypotheses if necessary.
- Communication: Sharing results with the scientific community.
Key Concepts
- Theory: Well-substantiated explanation of some aspect of the natural world.
- Law: Statement based on repeated experimental observations that describes some phenomenon of nature.
- Variable: Any factor that can change in an experiment; includes independent, dependent, and controlled variables.
- Peer Review: Evaluation of research by experts in the field to ensure validity and reliability.
Importance of Science
- Expands knowledge and understanding of the universe.
- Provides technological advancements and innovations.
- Informs public policy and decision-making through evidence-based approaches.
- Aids in addressing global challenges such as climate change, health crises, and resource management.
